Particle Emitter ZOffset not working!

I just made a speedlines effect and I noticed the particles where clipping through the walls. So I turned up the ZOffset to 5 and over (which i thought was already enough) but it still clipped through the walls. I also noticed that if u set the ZOffset to 8 or over the effects just wouldnt show up.


Plsss let me know if anyone has found a solution!
if not how can i make re make the speeed lines so that it wont clip through the wall
